PIPE-ORGAN.

SPECIFICATION forming part of Letters Patent No. 468,509, dated February9, 1892.

Application filed December 6, 1890- Serial No. 373,731. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN Soorr VoTEY, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Pipe-Organs; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in pipe-organs;and it consists in a novel arrangement of parts operated by and inconjunction with the stops of the organ, whereby a corresponding seriesof lovers may be pneumatically actuated to set a series of plungers in acylinder or revolving agent for the purpose of arranging them in suchmanner as will enable the operator, when subsequently executing themusic, to readily and easily produce any desired combination ofregisters or any number of consecutive combinations of registers,according to the music-score, by a manipulation of the fingerrail, and afurther arrangement of parts operating in concert therewith wherebyduring the execution of the music the stops that correspond with eachconsecutive combination of registers are pneumatically adjusted when thecylinder to produce a certain combination of registersby pneumaticaction, and to further provide for pneumatically actuating and lockingthe corresponding stops when said combination is produced, at the sametime operating the slides that control the several registers to be usedto do away with the intricate and complicated mechanism usually employedfor this purpose and obviate the noise incident to its operation, whichis in some cases so great as to seriously impair the tone of theinstrument. This object is attained by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a longitudinal sectionthrough that portion of an organ containing my improved features. Fig. 2is a plan view of the parts shown in Fig. 1.. Fig. 3 is a longitudinalsection on dotted line 1 1 of Fig. 2. Fig. 4 is a transverse section ondotted .line 2 2 of Fig. 2, looking to the right.

The drawings illustrate my improved features as applied to athree-manual organ; but they may be adapted to an organ of any number ofmanuals.

Referring to the letters and figures of reference, A indicates theordinary frame of the organ, having on the front thereof the keyboards BB' B", provided with the keys 0, that are connected to operate in theusual manner.

A indicates a cylinder mounted to rotate in the frame of the organ, andby suitable mechanism (not shown) is placed under the control of theoperator. Said cylinder is provided with a series of plungers '12,mounted to slide on pins 0, set in the circumferential grooves n in theperiphery of the cylinder and arranged in longitudinal rows therein,which is common. The plungers n are adapted to slide out and in on theirrespective pins 0 and are provided with a peripheral groove 0', adaptedto receive a longitudinally-working slide 15 to lock said plungers intheir innermost position, said plungers being locked in their outermostposition by the slides 15 passing between their inner shoulder and theperiphery of the cylinder A. This arrangement permits all of theplungers in any of the longitudinal rows to be locked by a single slide,either in their outer or inner position, or with part of them out andpart of them in, as shown by the lower line of plungers in Fig. 4. It isby the previous arrangement of these plungers in the cylinder A,according to the music-score, that the operator is enabled to readilyand easily produce any desired combination of registers when executingthe music, as hereinafter set forth.

The setting of said plungers in the cylinder is accomplished in thefollowing manner: Extending through the front of the organ, on each sideof the key-boards, are a series of stops D, that are adapted to slidehorizontally.

A continuation of said stops D is effected by coupling the rods Dthereto, the rear end of each of said rods passing through air-chamhersI) 1), formed in the case D, as shown in Fig. 1, said rods having on theend thereof the convexed buttons at a, that bear against the outer facesof the flexible diaphragms (Z (Z of the respective air-chambers Z) b. By

this arrangement, when air under pressure is admitted alternately to thechambers Z) b through the pipes E E, the respective diaphragms (Z d ofsaid chambers will be alternately blown out, and said diaphragms hearingagainst the buttons a a of the rods D will cause said rods toreciprocate longitudinally and move the stops D out and in for purposeshereinafter described.

Mounted on the rear ends of each of the stops D is an inclined arm f,adapted to engage the lower ends, respectively, of the vertical stems f,carrying on their upper ends the valves 2?, adapted to close theirrespective portsf in the wind-chest F, said stemsf' also carrying thedisk t, adapted to close the outer opening of the portf when the valves75 are raised, whereby by drawing outward on the stops D the arm fthereon will operate the stem f to raise the valve 6 in the windchest Ffrom the port f, when the wind will pass through said port into the pipeF, communicating therewith, and through said pipe into the air-chamber7t in the chest F. Said air-chamber communicates with a flexiblediaphragm h, that bears against the button a on the upper end of thevertical rod h, said rod passing through the air-chamber h and theair-chamber m of the case G, and, extending through said case, iscoupled at its lower end to one end of the horizontal lever H, which isfulcrumed near its longitudinal center to a support H, the opposite endof said lever carrying a friction-wheel H and being held up by a springt, which causes said wheel to normally bear against its correspondingplunger 01 when said plunger is in its innermost position in thecylinder A, by which arrangement, when wind is admitted to theair-chamber 7L through the pipe F, as before described, the diaphragm hwill be blown out, actuating the rod h and raising that end of the leverH to which its lower end is attached, depressing the opposite end ofsaid lever upon the spring i, and carrying the wheel H down, when itscorresponding plunger n will fall to its outermost position in thecylinder A, as shown in Fig. 1 and at 'n in Fig. 4. It will beunderstood that the number of plungers n in the longitudinal rows on thecylinder A correspond with the number of stops D of the organ and thateach stop operates a separate lever H to set its corre sponding plunger,which enables the operator, by drawing out the respective stops D, toset their corresponding plungers it in the cylinder A to produce thefirst desired combination of registers. \Vhen said series of plungersare so set, the locking-bar or slide i is actuated to lock said plungersin their respective positions. The stops D that were drawn out to setsaid combination are then shoved in, when the valve twill close theupper end of the portf, cnttingotf the wind from the air-chamber h, thewind therein being permitted to escape through the lower end of the portf, opened by the dropping of the disk i, thereby relieving the lever H.The cylinder A is then revolved by suitable means to bring thesucceeding row of plungers 01 directly over the series of wheels carriedby the levers II, when by again drawing out the stops said row ofplungers may be set for the next combination of registers, according tothe music-score, when said plungers are looked, as before described, andthe cylinder A again revolved to bring another row of plungers inposition to be operated on by the levers I l, and so on until all of thehorizontal rows of plungers in the cylinder have been set, or as many ofthem as is necessary to pro duce consecutively the differentcombinations of registersin the music to be executed. The cylinder A isthen revolved until the row of plungers a set for the first combinationshall stand directly over the wheels ll" of the levers H. The music maythen be executed in the ordinary manner, and when it is desired toproduce the first combination of registers set the operator strikes uponany one of the finger-rails I, that extend along each manual of theorgan, conveniently above the keyboards thereof, (see Fig. 2,) and theinner ends of which are pivoted at a: to the organ-frame and which areconnected by the coupling-rod I to the outer end of the lever 1",that isfulcrumed at its longitudinal center to the post Q, (see Fig. 3,) theinner end of said lever I being coupled to the vertical stem 1*,carrying on its upper end the valve .9, adapted to close the port 5 inthe wind-chest F, said stein also carrying near its center the disk 3,adapted to close the outer end of said port when the valve 3 is raised,whereby, when the operator strikes the finger-rails I,the lcverl isoperated to raise the valve 3 in the windchest F, when the wind willpass through the port 3 into the pipe G, communicating therewith, andthrough said pipe to the air-chamber m in the case G, in which islocated a two-way valve P, controlling the ports 11 t", thatcommunicate, respectively, with the pipes E E. This air-chamber m iscommon to all the valves P of the series of levers H, the position ofsaid valves being determined by the position of the plungers n in thecylinderA. For instance, those plungers that have been set in theiroutermost position will bear upon the wheels 11 of the levers H, therebydepressing that end of said lever and raising the valve P, connectedwith the opposite end thereof, as shown in Fig. 1, which will open theporto, permitting the wind to pass through the pipe E to the air-chamberb and expand the diaphragm d, which will blow out its corresponding stopD and raise the valve 2i in the wind-chest F,when the wind will blowthrough the pipe F into the air-chamber 71 and raise the diaphragm It,thus drawing upward on the rod h and locking the valve P and lever H intheir respective positions. At the same time the wind will pass from thechamber h,- through the pipe J, into the air-chamber 0 of the case N andraise the flexible diaphragm 0, which bears against the button 0" of therod 11;, on which is mounted the two-way valve 10., controlling theports i i in the windchest J, through which said rod passes, therebylifting said rod and raising said valve from the port 1'" when the windwill pass through the pipe K and expand the bellows L, which, beingconnected to the twin bellows L by the rods 2, will cause said bellows Lto collapse and actuate the slides that control their respectiveregisters, (which construction is not shown, as it will be readilyunderstood.) The blown out, when the desired register or combination ofregisters will be produced, ac-

cording to the previous arrangement of the plungers n on the cylinder A.After the first combination has been used the cylinder A (by suitablemechanism,'not shown) is revolved so as to bring the succeeding rows ofplungers 'n directly over the wheels H, carried by the series of leversH, when the plungers n that are set in their outermost position willbear upon the wheels H" and depress that end of the lever H on whichthey are mounted, actuating the opposite end of said lever to raise thevalve P to open the port 1, as shown in Fig. 1, and the spring 5 willforce the wheels 'H up against the plungers n, that are set in theirinnermost position, as shown at n in Fig. 4, thereby drawing downward onthe rod 71:" and actuating the valve P to close the port 1 and open theport '0, the parts being then in position to produce the nextcombination, the operation continuing in the same manner until all thecombinations set have been used in their consecutive order. When thewheel I is resting against a plunger in its innermost position, thevalve P will close the port '1) and open the port Q2, so that when thefinger-rail is struck wind will be admitted through the pipe E to theair-chamber b, which will blow out the diaphragm d, drawing in itscorresponding stop D, which is thereby locked in that position whilethat combination is being used, it being undcrstoodthat it is theplungers set in their outer positions only from which any effectis-obt-ained.

It will be observed that the ports 1; o in the wind-chest G areprovided, respectively, with the vents 1 2, adapted to be closed by thedisks 3 4, mounted on the rod h, the position of parts being such thatwhen the valve P is raised to admit wind to the chamber to blow out thediaphragm d the disk 3 will be raised from the vent 1, which permits theair to escape from the chamber 7) through the pipe E as the diaphragm dis drawn in, (shown in Fig. 1,) and when the valve P is down, openingthe port o to permit the wind to pass through the pipe E and blow outthe diaphragm d, the disk 4 will be carried away from the vent 2,permitting the air to escape from the chamber 1) through the pipe E asthe diaphragm d is drawn in. It will also be observed that when thevalve t is closed the disk 25 is moved away from the outer end of theportf, which affords a vent for the airchambers h and 0 through thepipes F and J, permitting the diaphragm 0' to collapse and the valve 10to fall, opening the port 6, when the wind will pass through the pipe Kto the bellows L, expanding said bellows and collapsing the bellows L,as shown by dotted lines in Fig. 1, when said parts are in position toagain actuate the slides to produce the register controlled by itscorresponding stop.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is-
